Larimer County District Attorney Cliff Riedel has filed multiple charges against Berthoud teen Tanner Flores, beginning the process of bringing the homicide case to Larimer County.

Flores is accused of killing 18-year-old Ashley Doolittle, his ex-girlfriend, last week at Carter Lake west of Berthoud before driving her body to near Collbran in Mesa County. Riedel has charged Flores with first-degree murder, kidnapping and using a weapon to commit a violent crime. Wednesday morning, a Mesa County judge dismissed the charges Flores faced there since he had been charged in Larimer County.

The Larimer County Sheriff's Office was unsure Wednesday when Flores would be transported to Larimer County.

Doolittle, who lived in Loveland, graduated this spring from Berthoud High School and planned to attend Colorado State University in the fall, according to her obituary published in several local newspapers as well as on CSU's website. She began riding horses when she was 5 years old and was a skilled rider and competitor.

She spent spent eight years as a member of Boulder County 4-H and served as vice president of Thompson FFA. She competed on national horse judging teams and was named the champion high individual overall in the National 4-H Western Roundup and state FFA competitions. Doolittle taught others about agriculture during her role as Boulder County Fair and Rodeo Lady-in-Waiting.

According to a Mesa County affidavit, Flores told police he shot Doolittle twice in the head because he was angry with her. He then drove her body about 280 miles away to his deceased grandfather's house in Mesa County. The two had been in a romantic relationship for more than a year when Doolittle ended it, the affidavit said. Flores was arrested the day after Doolittle was first reported missing by her mother.

Doolittle is survived by her parents Jeff and Ann Marie Doolittle and brothers Michael Doolittle and Branden Kratochvil.

A viewing will be held 4 to 7 p.m. Thursday at Viegut Funeral Home, 1616 N. Lincoln Ave., Loveland. A Mass of Christian burial will be held at 10 a.m. Friday at St. John the Evangelist Catholic Parish, 1730 W. 12th St., Loveland. Interment will follow at Greenlawn Cemetery in Berthoud.
